Application led November 24, 1916. Serial No. 133,185.

Be a known um; i, DORSAY 'MboALL -TVHITE, a loyal subject of the King of England, and resident of Detroit, Wayne county,

State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification.

This invention relates to hydrocarbon motors and particularly to cooling systems especially adapted for use therewith.:

One of the objects of this invention is'to provide a cooling system, with improved means for controlling the temperature of the cooling medium, and for regulating its circulation.

Another object of this invention is to provide a hydrocarbon motor, having improved means tory circulating the cooling mediumthrough various jackets in 'independent parallel" paths, with a common radiator and regulator' for controlling' the circulation thro ugh said paths.`

Another object of my invention is to pro-l vide an improved regulator for circulating systems,l and also an improvedv mounting and arrangement of such a regulator adapted to the cooling system of a hydrocarbon' motor.

'The system illustrated embodies a motor having itscylinders arrangedy in relation,.- each jacket having independent circulating y j paths to and through it; a common regulator, radiatorbypass, and connections com` plete the various circuits.

The various objects and novel featurespvof l this invention will lclearly appear from the following description taken -in connection with the accompanying drawings, vWhich forni a part of this specification, and in Whichz l Figure 1 is amore or less diagrammatic side elevation, with portions broken away,

V `of a motor vehicle power plant embodying 'construction shown in Fig. 1;

this linvention F'g. 2is a fragmentary plan view of the Fig. 3 is a vertical sectional yiew substantially on the line 3 3 of Fig. 2, showing the. Valve mechanism in one position;

Fig. 4 isa view similar to Fig. 3, with the vaive in another position;

crank case 11. Each block is provided with` a cooling jacket 14:, having an inlet port 15 and an outlet port 16; A tandem pump mechanism 17, of an well known construction may 'be mountedI adj acent the front end of the' motor and. driven therefrom, as desired. TheV pump mechanism is provided withan inlet port 18, and a plurality of outlet ports 19. Each of these outlet ports is independently connected to a jacket inlet port 15, by a conduit 20.

,A common radiator 21 for thejackets may 4be suitably mounted ona frame front cross member 22, as by bolts 23, the radiator being provided adjacent its upper end with an inlet port 24,' and adjacent its lower end y .with Yan outlet port 25.

A flexible conduit 26 connects the radiator -outlet port 25 with the pump inlet port18. `A pair of iexible conduits 27 connect the jacket outlet ports 16, with a common re'v turn' 28, which is mounted on the radiator 2L `A bypass 29, around the radiator, is arranged between the common return 28, and the pump Lmechanism 17, adjacent its inlet port1& A

'A valve chamber 30, is'suitably arranged or. formed in the return 2,8. This valve chambenis provided with a lateral port 3l eov in register with the radiator inlet port 24. Y

The chamber is also provided with valve'v ports 32, and with a port 33 in its lower` detachable end wall 34:. The upper endof the bypass 29, may be secured to the nipple 35, the interior of whichis in constant com- Amunieation with the chamber end `port 33. The upper portion of the chamber is provided with a pair of inlet ports 35', which are in` constant communication with the jacket outlet. conduits 27.

A thermostat 36 comprising a corrugated `collapsible resilient tube, whichmay 'be charged with any suitable thermo-sensitive liquid or vapor, may be secured to the upper .end wall 37 of the chamber as by a threaded stem 36. lA valve member 38 is suitably secured to the lower free end of the thermostat 36. This valve member is provided with an end portion 39, and a tubular upwardly extendingor inturned tubular 'portion 40. The portion 40 has a plurality of ports v41 formed therein, adapted to coperate With'the ports 32 in the chamber. The tubular portion 40 of the valvek member 38, is adapted to control the iow of the cooling medium through the chamber lateral port 31 by opening and closing the regulating ports 32, and the end portion 39 of the valve member is ada ted to'control the circulation of cooling me ium f through the chamber end port 33. 20 The operation of the preferred embodl- =ment of this system will be understood from the foregoing description', to be as follows Assuming the motor and pump vmechanism 17 to be started when the temperature of the cooling medium within'the jackets 14 isbelow the 'desired limit, the thermostat 36 will contract, thereby raising the valve member 38 to the position illustrated in Fig. 4. It will be not'd that the ports 4l are out of register with the ports 32, and the port 33-in the bottom of the chamber is unrestricted. With the valve mechanism in this 'osition, the cooling medium will circulate'fiom the pump'mec anisml 17 through the independentv conduits 20, jackets 14,

connecting conduits 27, common return 28` entering the valve chamber through ports 35', bein discharged from the chamber through t e lower en d port 33, and returning to the 'pump mechanism through the bypass 29 around the radiator. n Thus it will be seen that withthe valve mechanism'in this position, there will be no circulation through the radiator.

When the temperature ofthe cooling mediumis raised by the heat generated within the cylinders to the desired upper limit, the thermostat 36 will be caused to expand, finally seating the end portion 39 of the valve member 38 over the port 33, and at the. same time bringing the ports 41 into register with the chamber ports 32. With the valve mechanism in this position, the circulation between the pump"..mecha nism and the inlet port 35 of the chamber, :will remain the same as described in'fconnection'withrthe other position of the valveA mechanism. However, on account of the It will be noted that a port 42 is formed in the upper part of the chamber 30 in constant communication with the interior thereof, and the radiator inlet port 24. This port, which is also in communication with the atmosphere, through the vent 43 in the radiator cap 44, prevents the formation of air or. steam pockets Within the system. It also permits the cooling medium to be drawn from the cooling system upon the opening of the drain cock 45, which is arranged at the lowermost portion of the pump mechanism 17, which is also the lowermost portion of the entire system.

While I have describedand will specifi'- se cally claim, what I deem to be a preferred embodiment of my invention, it willl be, of course, obvious to those skilled-in the art, that various modifications, changes and adaptations may be made without departing 35 from the spirit and scope hereof.
